Emflon® PFR Filter MediumAt the heart of every Kleenpak Emflon PFR Capsule filter is a high-performance pleated cartridge, containing proprietary PTFE membrane. The high-strength PTFE membrane is inherently hydrophobic, chemically inert, and designed specifically for removal of contaminating bacteria and viruses. Emflon PFR filters have a microbial removal rating of 0.2 µm in liquids and a particulate removal rating of 0.003 µm in gases. Emflon PFR filters meet the ever-increasing demand for air filters with greater strength and longer life.
Clean and Robust DesignThe Kleenpak filter uses well-proven proprietary Pall techniques for filter construction and heat sealing.
- The highest possible security against filter bypass is ensured, even under conditions of pulsed flow
- High-strength design allows multiple autoclave cycles for extended use and maximum filter economy
- Polypropylene outer shell is designed to provide long-term assurance of pressure and temperature ratings
- A total absence of glues, binder resins and surfactants results in very low filter extractables and extremely clean filtrate
High Quality StandardsEvery Pall Kleenpak filter is manufactured to a very high standard of quality assurance and cleanliness, and in accordance to a quality system accredited to ISO 9000.
For pharmaceutical use, the P designation in the part number provides full traceability supported by a certificate of test.
